Job description

Attributes We Value

We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you’re motivated by our mission and operating principles. You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor.

You're humble and collaborative; turn zero‑to‑one ideas into real products, and you get stuff done end-to-end. You use AI to work smarter and solve problems faster. Here, you’ll tackle complex, high‑visibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let’s build what’s next.

About the team

Our Mobile Team is responsible for the end-to-end development of both our iOS and Android apps, leveraging the latest technologies to build a seamless user experience. On iOS, we work with SwiftUI, Combine, and Async/Await, while on Android we use AndroidX, Coroutines, Hilt, and a suite of Jetpack libraries.

You’ll be joining Airwallex at a pivotal moment as we expand the capabilities of our modern, fully native mobile apps. These apps empower customers to manage global B2B payments, submit and approve expenses, and control both virtual and physical Airwallex cards—including seamless Apple Pay and Google Pay integration for card transactions.

What you’ll do

As a Mobile Engineer, you’ll focus on building high-quality, user-friendly native mobile applications using modern frameworks and best practices. You’ll work closely with product managers, designers, and other engineers to deliver features that are reliable, intuitive, and performant.

This role can be based in Singapore or Melbourne.

Responsibilities

• Take ownership of the design, implementation, and delivery of key features across our iOS and Android apps, ensuring they are intuitive, performant, and reliable.
• Collaborate closely with fellow engineers to define architecture, share best practices, and drive high-quality standards across platforms.
• Influence how we scale and evolve our mobile apps—built less than three years ago—by shaping core architecture and contributing to long-term technical direction.
• Go beyond feature development: contribute to team processes, product decisions, and broader engineering strategy as we scale globally.
• Be a hands‑on technical leader who takes pride in clean, testable code and actively supports continuous improvement across the mobile stack.

Who you are

We’re looking for people who meet the minimum qualifications for this role. The preferred qualifications are great to have, but are not mandatory.

Minimum Qualifications

• 6+ years of experience developing native mobile applications on iOS or Android, using modern frameworks and development practices
• Bachelor’s degree or higher in Computer Science, Engineering, or a related field
• Proven experience shipping one or more production apps, ideally available in the App Store or Google Play
• Strong focus on code quality—writes testable code with high test coverage
• Experience maintaining CI/CD pipelines (e.g. GitHub Actions, Bitrise)
